Abstract

Abstract : The fragmentation of uracil molecules and pure and nano-hydrated uracil clusters by 12 C 4+ ion impact is investigated. Abstract : The fragmentation of uracil molecules and pure and nano-hydrated uracil clusters by 12 C 4+ ion impact is investigated. This work focuses on the fragmentation behavior of complex systems and the effect of the environment. On the one hand, it is found that the environment in the form of surrounding uracil or water molecules has a significant influence on the fragmentation dynamics, providing an overall 'protective' effect, while on the other hand we observe the opening of specific fragmentation channels. In particular, we report on the first observation of a series of hydrated fragments. This indicates a strong interaction between uracil and water molecules, holding the water clusters bound to the observed molecular fragments.
